Microsoft Exchange Publishing Considerations

TAC can publish Exchange 2003, 2007, 2010 and 2013 versions.  Exchange uses many additional services to serve Exchange clients. TAC also provides the facility not to miss those services through its publishing site. TAC supports all features of Exchange in publishing including Outlook Web Access, Outlook Anywhere and Exchange ActiveSync. 

When publishing Exchange 2007 and above versions, you might need to publish its additional component service, Outlook Anywhere. In this case, you need to publish Outlook Anywhere as a separate application in TAC and you also need to publish its additional dependency services Microsoft Exchange Autodiscover and Microsoft Exchange Web Services as separate applications. The Autodiscover service configures and maintains server settings for the Outlook clients. When Autodiscover is set up, Outlook clients are not required to enter server details; email address and password, and all the other settings will automatically be setup and configured.  

For more information about this Exchange feature, refer to the Exchange 2007 Autodiscover Service white paper: https://technet.microsoft.com/en-us/library/bb332063 (EXCHG.80).aspx. 

Exchange Web Services (EWS) is a collection of Web services enabling client applications to communicate with the Exchange server via an XML messaging interface.  

For more information, visit the following URL, which provides an introduction to Exchange Web Services: https://msdn.microsoft.com/library/aa579187.aspx 

Exchange Autodiscover and Exchange Web Services are available in Exchange versions 2007 and above only. Exchange 2003 does not provide these facilities with its configuration. 

It is also important to note that though these services are part of Exchange application configuration and publishing, there is no linking between those support applications of Exchange and primary Exchange application. If you do any modification to the Primary Exchange application properties, you may be required to manually modify or update related properties on the other two applications and vice versa. 

Furthermore, TAC can publish Exchange ActiveSync as a separate application (as a service application for primary Exchange application) that allows mobile devices to synchronize data with Exchange mailboxes. Synchronizing is a process of reconciling data between a device and the appropriate Exchange mailbox. Exchange ActiveSync is a protocol. The protocol synchronizes your mail, calendar, contacts, and tasks over the air with Microsoft Exchange Server.  

It must be noted that when adding application related to Exchange, administrator will be required to consider about host header properties of the Exchange and TAC application publishing. If the Public Host name of the TAC application property field matches the external host name of the Exchange services that you publish you would not require to select and enter “Replace Host Header with following” option. If TAC application public host name does not match, administrator needs to enter the internal host name of the Exchange service in the “Replace Host Header with following” field. Administrator can get the internal host name of the Exchange applications (OWA, ActiveSync, OutlookAnywhere) through Exchange Management console.

To publish Exchange support service applications, do the following: 

  1. Open TAC Configuration Console and select the site where you published Exchange application 
  1. Click Add under Applications 
  1. Select Web and select the Exchange service that you intend to publish from the dropdown 
  1. Click Next 
  1. Enter name for the application 
  1. Click Next 
  1. Select Server-type: Single application server or farm of application servers. 
  1. Click Next 
  1. Provide Application properties 

a) In Address field, enter Exchange server address  

b) Select Port 80 for HTTP or Select Use HTTPS (SSL) for secure connection 

c) Under Path, required Path is added from the template; we do not recommend making modifications. 

d) Enter public host name 

e) Select “Replace Host Header with following” to match the host header with Exchange settings (External URL of the exchange service) and enter the host header of the external URL of the exchange service in the field. If the public host name and the external URL of the exchange services in Exchange are same then this option is not required.
